can someone tell me what is the spark plug gap inches for a 1998 Buick Regal GS supercharged?
Agree with .060 gap. If you are going to use Double Plat or Iridium just check the gap but don't adjust if it is wrong you will damage the plug electrodes, take it back to the parts store and get another one. Don't forget to use a little anti seize compound on the threads.
